To all whom it may cameron j Be It known that I, RAS CRAIG, a citizen of the United States, and a resident-of Los Angeles, in the County of Los Angeles and.

State of California, have invented a new and Improved WaveMotor, of "which the following. 1s a full, clear, and exact description.

This linvention relates to motors devised.

I for utilizing the force developed by the rise and fall of waves of the seaol other body of` water.

The purpose of the invention isto. provide novel details of construction. for a wave mo.- "tor, which when` assembledli-n a concrete ap.-

paratus, eiect the positive yandcon.tinuous conversion of the force owaves yduring their `rise andsfall, into rotary motion of a driven shaft for the actuationof other mechanism. The invention consists inthe novel construction `and combination of parts, as is hereinafter describedand A.defined in the appended claims. I

Reference is to be had to. the accompanying drawings forming a partof this specifi- Ication, in which simllar characters of reference indicate corresponding parts in all the views. l

Figure 1 representsa partly sectional and broken side` view of the improved motor erected on a beach andhaving a'portion thereof immersed-in a body of .Water for actuation by waves thereof, the section being defined by the line 1-1 in Fig. 2; lFi g..2lis a transverse sectional view, substantially on the line 2-2 in Figi 1; Fig. 3 is an end view of the Wave motor seen in thedirection of the arrow in Fig. 1 Figy'4 is an enlarged sec-1 'tional plan view of details, substantially on' y theA line 4-'4 in Fig. 2; Fig. 5 is a transverse sectional view of parts., substantially on 'the line 5 5 .in Fig. 2; and Fig. 6 is a transverse sectional view, substantially on vtheline 6 -6 in Fig.`2. l

`As 'the motor is specially adapted for utilizing the impact of waves of a sea or ocean, it is necessarily erected 'on the beach of such a body of water, as is indicated at A {in the drawings. i

The preferred form .of structural supports for the operating mechanism, consists of three frames erected in sequence on the beach A, and which for' conveniencemay be respectively designated a guide frame, that is in the water, a fulcrum supporting traine p next to the guide frame, anda tower frame incline toward the upper ends of the stan- 11,0

'getlier by bolts a, a.

that.' supports the mechanism' employed for the conversion .of reciproeatingI motion into continuous rotary motion, as will hereinafter be fully described; y

.A principal detail'of the invention is the form'of an elongated power lever 10 that is rockably su orted on the fulcrumframe at a suitable Istance from the ends thereof To insurestability, a strong skeleton frame is provided for a fulcrum base, consisting essentially in the provision of sill. beams 11 on the end pnrtions of which are erected posts 12, four in number, two appearing in Flg. 1.- The posts 12. all incline toward each other 'and are spaced apart byl horizontal timbers 12 near their lower ends, and cap timbers 12F that are' seated on the upper ends thereof, ythese horizontal timbers being bound t0.-

Upon. the Gap timbers., pedestalfblocls, such as b are mounted and secured, and upon the lower.` side of the power lever 10, a similar block b is secured y bolts, these paired blocks being hinged together, as shown at c, which adapts the power lever for rocking movement on its fulcrum support. -Upon the outer end or1 thelever 10, that eXtendsover the body of Water A, a hollow Heat 13 is4 secured, which is semiglobular in form, is of properfdimensions for effective service, and 1s .hermetically sealed by a water-tight cover.

The guide .frame structure, comprises a i stanchions'b'eing arranged to produce a rectangular structure and ,at their lowerends, are sharpened to. ermit said ends 'to be driven down into t e ground nearI the body of Water Whichreceives the ioat 13. O f the vertical stanchions mentioned, there .eretwo pairs 14 -which are positioned so las to reoeive the power lever 10 between them, and

'upon the inner or adjacent surfaces of each pair `of said stanchions, a vertical guide .d is

'securedupon each, these pairs of guides receiving the impingement of antiffriction rollers e that are mounted upon the opposite 'sides ofthe power lever 10, and thus give lateral su pport thereto. c The guide frame is preferably reinforced by other vertical posts 4 ,l

14b that are erected nearest the fulcrurn supporting frame, and at-tlle upper ends thereof, are joined to horizontal beams 14C whichare also secured upon the stanchions 14.

andco-act with the gears lf'or turning the shaft 1.9 always in the samerdirection, it will be obvlous that the reciprocation of the racks 18, due to the oscillations ofthe power lever A10, will ive continuous rotary motion to the 1 shaft, w ile the-'water'A is agitated by asuecession of waves.

(with the teeth ofthe ratchet whee, as. is

movement of the shaft 19.

In further explanation, it will be seen that'. upon the inner nd of the power lever receivlngan upward impulse, one rack, shown in Fig. 6, will byturning the spur gear it isineshed with," also turn the corresponding 'ratchet wheel 21, due to the pawl m on said gear interlocking with the teeth l of the ratchet wheel, and this rotary motion wil continue while the rack is moved upward.

Inspection of Fig. 1 wil-l show that the dcscribed operation of the rack, gear and ratchet wheel, is produced by the prepondcraiicev of lweight had by the long arinof the power lever 1Q when a wave is receding and the float 13 descends a corresponding degree.

When the next wave impulse commences to elevate the float 13 and the outer end of the power lever, the gear 20, shown in Fig. 5, that engages with the other rack anivtzlhat had been dorinant, diie to the slippingI of the pawl over theadjacent ratchet wheel, n'ow `ecoines active, as said pawi wil intel-toet:

shown in Fig. 5 and continue the rotary 1t wi;l lie apparent that the support ofthe power lever 10 at a point much nearer to the racks than to the loat, gives increased level-agote the longer, member of the lever and a corresponding` increase in power for the short ineinber thereof, which is transniittedto the shaft 19 by the' ineanshereinbefore described. f i v Having thus described my invention, l claim as new and desire to secure by Letters Patent: Y
